In my dream world, I would like to lose 50 lbs, but realistically, I would be/look OK loosing 10-15 (I carry weight very well). In spite of that, I've continued dating and recently met SO. He is begging me not to lose any weight. Everything I want to change about my body, he loves. Different men like different things, so I say go for it. It's a very interesting confidence booster, but if we were to break up, I'd go back to being serious about weight loss because I know he is the exception rather than the rule.
